The myth of one people

The notion that the Japanese form a single, homogeneous people is a deeply entrenched premise today, yet unraveling how this view took hold is no simple matter: it involves the narrow horizons of modern scholarship as well as a tangle of political currents. Having no ties to academia myself, I have spent years examining history, culture, customs, and faith as an integrated whole. I cannot agree with the academic consensus of a homogeneous population; instead, I look to a heterodox view that has been quietly maintained alongside it — one that sees life in the Japanese archipelago as a series of overlapping strata. For convenience here, I will call this the "multilayered view."

At the same time, however, we have to account for how the diverse origins of the people of the archipelago were gathered into a single narrative during a particular historical era, giving rise to the idea of homogeneity in the first place. Simply debating which of the two views is right or wrong is pointless; what is needed is a careful, deeper inquiry drawn from the integrative perspective distinctive to Japanese thought.

Across the ancient strata of Japan, complex, still-unexplained interminglings of peoples occurred everywhere. In recent years, genetic analysis has spread into archaeology, generating a wave of celebrated new hypotheses. Yet there remains the same tendency to equate these findings directly with "the reality of the Japanese," which I see as only the latest obstacle to a true understanding of Japan. Genetics can serve as a reference, but it cannot disclose the complexities of cultural blending, and because its results depend heavily on the specific individuals sampled, it cannot give us a complete picture of the peoples of the Jomon, Yayoi, or Kofun periods.

If we set aside contemporary politics and look calmly at Japan's geography and history — an island nation at the eastern edge of the Eurasian continent — it is impossible to rule out the arrival of many peoples from across Asia over the millennia. While most came by way of neighboring China and the Korean peninsula, traces of migration from Southeast Asia, Central Asia, and even as far afield as Persia can be read in the historical record. These intricate lineages mingled over thousands of years to form the modern Japanese. How, then, did a view of the Japanese as a homogeneous group — one that leaves out all this complexity — become the majority position?

Several modern scholarly lineages played a part in this, but here I want to examine one of the chief pillars supporting the idea of a homogeneous population: the "rice-centered theory."

The rice-centered theory begins from the claim that rice cultivation — specifically wet-rice farming — shaped a single Japanese culture, and it interprets history as a whole through the equation of "the Japanese = wet-rice agriculture." The figure who laid the foundation for this school of thought was the folklorist Kunio Yanagita (1875–1962).

While Yanagita achieved monumental work as Japan's pioneering folklorist, he clung throughout his life to the idea that "the Japanese are a people of rice cultivation," organizing the folk customs of the archipelago without ever letting go of this premise. His rice-centered theory held that the Japanese share a single culture as wet-rice agriculturalists; within his folklore studies, he proposed the concept of jomin (常民) — the common folk — and defined them specifically as settled farmers who cultivated wet-rice paddies.

Yanagita pointed out that even in mountain villages, people held a special reverence for rice. "For food, they may eat foxtail millet or barnyard millet," he wrote, "but to worship the gods, there must without fail be rice." Here his core conviction is unmistakable. Starting from this premise, he emphasized that even in the most remote villages, people strove to grow rice in order to make offerings to the gods. In other words, even where daily meals consisted of coarse grains, rice was unfailingly used on sacred, ceremonial occasions known as hare (ハレ). Yanagita saw this custom as the shared cultural bedrock of the entire archipelago, and upon it he built his theory that the Japanese share a single, unified culture.

Yanagita's work is certainly a valuable point of reference, yet we must be wary of how, in order to bolster his own thesis, he invariably placed rice culture at the center whenever he inquired into the origins of the Japanese. The culmination of this effort was the book of his final years, The Sea Road (1961). In it, he argued that the ancestors of the Japanese were people who carried rice and rice-related beliefs northward from the southern islands until they reached the Japanese archipelago. This image of "rice cultivators arriving from the south" is a prime example of how Yanagita sought the wellspring of Japanese culture in rice. In the school of "Yanagita studies" that followed in his wake, nationwide similarities in annual village observances and agricultural rites — such as rice-planting and harvest festivals — were given overriding weight, leading to the extreme posture of ignoring forms of faith unconnected to rice.

For the few, like myself, who see the Japanese not as a single homogeneous group but as overlapping layers, the very presences ignored by Yanagita's school of folklore are likely older in origin than wet-rice cultivation, and we cannot endorse an attitude that sweeps them aside wholesale. Yet the commonalities Yanagita proposed were held up as proof of the spiritual unity of the Japanese people, and for decades were bound up with the idea of national oneness with the emperor at its apex. Yanagita's rice-centered theory exerted an immense influence not only on folklore studies, but on prewar and postwar discourses on Japanese identity at large, becoming a major prop for the homogeneous view of the Japanese built around a core of rice. The lives of the people in the blank spaces excluded from this inquiry continued to be ignored; those who neither grew rice nor enshrined it were treated as though they were not Japanese at all. The greatest piece of propaganda born of this view is the insistent claim that "rice is the staple food of the Japanese."

The thinker who earliest harbored doubts about Yanagita's framework was the folklorist Shinobu Orikuchi (1887–1953), whom I have touched upon several times in these pages. Refusing to go along with Yanagita's homogeneous image of the Japanese, Orikuchi patiently investigated the ancient strata Yanagita had passed over, publishing one study after another and, in my view, laying the foundations of a true Japanese folklore studies. Yet because Yanagita was revered as the father of the discipline — and because his premise of a homogeneous people suited the prewar and wartime military, particularly the Army — Yanagita was overwhelmingly lionized, while Orikuchi was treated as a heretic and given far less weight.

The picture becomes clearer if we see the field as having split between "Yanagita folklore," premised on a homogeneous image of the Japanese, and "Orikuchi folklore," premised on multilayered ancient strata. In my own view, reading Orikuchi's essays is essential for anyone who wishes to understand Japan and the Japanese; conversely, the countless treatises on Japanese identity that fail to grasp Orikuchi are heavily colored by the subjective biases of their authors and require caution. And it was a scholar from Orikuchi's lineage who brilliantly refuted Yanagita's rice-centered theory: the folklorist Hirofumi Tsuboi (1929–1988).

Today, however, Tsuboi's name has been almost completely forgotten and goes largely ignored. To my mind, the folklore studies of the Orikuchi–Tsuboi line are the true achievement that unlocks Japan, yet for those who cling to a homogeneous image of the nation, their findings are deeply inconvenient. The chief reason Tsuboi is passed over lies in his 1979 book Taro and the Japanese. In it, Tsuboi challenged the arbitrary, rice-centered view of history and folk custom that had prevailed since Yanagita, drawing on decades of fieldwork to contest Yanagita's vision of the Japanese.

Put briefly, Tsuboi demonstrated that distinct cultural systems centered on crops other than rice survived in vivid form across the archipelago. In contemporary Japan, eating mochi (pounded rice cakes) at New Year's is generally taken for granted as traditional culture, yet this view too stems from Yanagita's rice-centered theory; in reality, there were once many regions across Japan where mochi was not eaten at New Year's at all. Tsuboi proved that in these regions, people instead offered and ate taro at New Year's. Going further, he brought to light traditional food cultures built around mountain yams, foxtail millet, barnyard millet, and other coarse grains, establishing the existence of peoples whose culture did not include rice.

As the reader may already suspect, coarse grains and tubers belong to the lineage of dry-field farming. Simply put, this stands in direct contrast to the wet-rice cultivation championed by Yanagita — and in fact, dry-field culture was once far more widely distributed across Japan. Tsuboi placed particular emphasis on slash-and-burn farming, a practice that has now dwindled to almost nothing and is for all practical purposes extinct. That is because cultures of this lineage were steadily driven out by the wet-rice culture of Yanagita's model. Indeed, rice culture has penetrated modern Japan so thoroughly that people now take rice to be their timeless staple, rice is enshrined in festivals across the country, and New Year's customs have almost everywhere been replaced by the eating of mochi.

This mistaken, subjective image of the Japanese constructed by Yanagita went on to influence the fledgling discipline of archaeology that was rising in the same era, eventually feeding into the wartime regime that bound the veneration of wet-rice agriculture to the worship of the emperor.

Takahiro Mitsui (三井崇央, born 1991), a Japanese philosopher, photographer and Yangmingist outside academia who has done his own fieldwork across Japan since 2019, makes his own argument in the essay “The myth of one people”, first written on 20 May 2025. Is Japan homogeneous? Homogeneity is a narrative built in one era from diverse origins, centered on rice, Takahiro Mitsui argues: overlapping strata, not one people — from a thinker with no ties to academia who studies history, culture, customs and faith as one whole.

In “The myth of one people”, Takahiro Mitsui writes about folklore studies, rice cultivation, dry-field agriculture and layered view, with Yanagita Kunio, Orikuchi Shinobu and Tsuboi Hirofumi. The place in the essay is Japan.

Takahiro Mitsui's thesis: the rice-centered theory, laid down by Kunio Yanagita, built a homogeneous people out of diverse origins (SJ 121, 2025-05-20).

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “What changes the nature of wa is not the praxis of a subject but the actual practice of everyday life.” (NO ONE DECIDED: Wa and the World's Most Orderly Society (2026), ch. 16, https://www.amazon.com/dp/B0HNP81CR3 )
